The objective of this study is to investigate the performance of Anaerobic Moving Bed Biofilm Reactor (MBBR) on the removal of organic matters (using COD, BOD5 and TSS values) in piggery wastewater using two kinds of carrier: Polyurethane (PU) and Polyethylene (PE) Different organic loading rates (OLRs) varying from 4.0 to 10 gCOD/l/day with controlled temperature 35 ± 2 o C, pH 7.0 7.5 were investigated. The seeded sludge was collected at the anaerobic tank of the wastewater treatment plant of the Sabeco Beer Manufacturing Plant (Nam Tu Liem district, Ha Noi) and grown in the MBBR for 15 days. For porous PU material, the COD, BOD5 removal efficiencies reached around 67 – 69 % and TSS removal efficiencies achieved around 55 – 65 % at OLRs of 4.0 and 6.0 gCOD/l/day. Whereas for wheel-shaped PE material, the all COD, BOD5 and TSS removal efficiencies were slightly higher with OLR of 6.0 gCOD/l/day: 71, 72.6 and 67 %, respectively. In addition, the PE seems to be slightly better than that of PU with the same OLRs of 4.0 and 6.0 gCOD/l/day. At 10 gCOD/l/day, all COD, BOD5 and TSS removal efficiencies tended to increase, reached about 73, 75 and 72 %, respectively However, TSS removal efficiencies were found to be higher with PE carrier at higher OLR, reaching 72 % at 10 gCOD/l/day.
